Data Acquisition

Abstract

This chapter provides essential concepts for a proper setup of the measurement hardware for OMA purposes. The main characteristics of different measurement schemes are summarized. Parameters characterizing the performance of sensors and data acquisition systems are illustrated, providing guidelines for their choice. Criteria for test planning and sensor installation are also discussed. Then, attention is focused on the main aspects concerning data acquisition and storage: setting of the sampling frequency, data streaming on file, and storage in MySQL relational databases. Tools for data validation and pretreatment are finally discussed. The applications proposed at the end of the chapter will guide the reader to the implementation of a customized measurement system based on programmable hardware.
